Assignment Project Description

Develop or use an existing parametric model in order to design and rapid prototype your geometries using a digital fabrication method of your choice.

Create a 3D object of an origami pattern

Inspirations & References

Fluid-driven origami-inspired artificial muscles



Grasshoper

I took the Grasshoper course tutorial. beginner in 3D, I found the interface with the linked boxes to be similar to the Scratch software, rather simple and understandable.

Afterwards, I got lost in the complexity of the project and the multiple parameters.


For my final project, I need to make an origami Design.

my first origami design was done on illustrator

laser engraved on paper, folding is easier. but the design wasn't precise enough, which distorted the folding and created tears.

Oripa

is a drawing software dedicated to designing the crease patterns of origami. The unique feature of ORIPA is calculation of the folded shape from the pattern.

1/ Create your origami pattern

I make two patterns :

Muria and Waterbomb

2/ you can export in .pdf to coreldraw if you want to ingrave the paper before folding

Freeform

Freeform Origami is a powerful application dedicated to simulating the folding or unfolding of paper models, based on the origami rules.

123dDesign

1/ the basic shape for my origami is composed of 3 rods with different sizes

123ddesignorigami_0026_calque_1.jpg

2/ I started by creating a polygonal shape with 3 sides to the dimensions of my folding

123ddesignorigami_0025_calque_2.jpg

3/The triangle is duplicated and positioned symmetrically on the smaller side

4/The second triangle

123ddesignorigami_0022_calque_5.jpg

5/The third triangle

6/ The second and third triangle are duplicated and positioned to form the 3D folding surface

7/creation of volumes is done from zero

8/ the point movement tool allows to create the origami folding volume

9/ By duplicating the basic volume, we obtain the shape of the folding in 3D

10/The basic form must be well grouped from the beginning, otherwise artifacts will appear

10/the form and counter-form are created

11/ a gap of 5mm is left between the origami surfaces for the silicone mold

123ddesignorigami_0006_calque_21.jpg

12/ 6mm holes are extruded in the origami recesses of the counterform

13/ you can export your .obj to shopboat or 3D Print

I Make a mold to create a 3D origami sheet with silicone

####################################################################################################################

3D Print PLA Mold

Clich here to see the 3D Print Mold Documentation

The holes in the mold being too small, I used a soldering iron to enlarge them and facilitate silicone pouring.

First I pour the silicone onto the bottom part and I put the top part on it. After I pour silicone into holes to try to fill the space to the maximum.

Silicone Demolding

My first test is not good, the silicone has only adhered to certain parts of the mold.


Screwdriver Marks on the Mold


Silicone Film

I try with Silicone Smooth-on SORTA-Clear™ 37 and Ecoflex

####################################################################################################################

SECOND 3D PRINT PLA MOLD

this time, I made a 3D design with a side opening into the mold to better pour the silicone and I choose the Mold Star™ 16 FAST (cure time of 3O minutes, better for fasting tests)

Second 3D Print PLA Mold


Holes in the Mold with a Soldering Iron (Mould pad)


Clamping the Mold to Pour Silicone


Silicone Demoulding After Drying

This time, the result is better, the silicone sheet is whole but the part opposite the opening of the mould is weaker, the silicone has not poured down well.
